You're a very kind and sincere person Misbah - I wish you all the best on your goals!
If I may - in the spirit of: not lying...I just want you to be very careful with the sentiment: "I will never want benefits in exchange." -- I understand what you mean, I understand the value and transparency of loving and giving others - because of purity of love and giving.
From my own life - I can tell you, there are many people (friends) who I don't doubt for one minute thought they were my "good solid friends" - who never took a moment to reach out and reciprocate when I placed the investment in keeping that friendship alive.
There will be a moment when I hope you will realize: friendships need to fill you, and need to consider the value you bring Misbah. While it's not the initial goal -- if and as soon as you notice, that there isn't value to you and others don't think of you as you do them...it leads to a painful realization when you find yourself "overlooked."
It's hard to describe to you in a comment - as (1) I can easily be misunderstood, (2) if you don't experience it, it seems petty or insignificant.
So, let it just be a random thought some random stranger told you today. If one day - in the right circumstance what I describe happens to you : I will want it to be clear to you:
You, Misbah - matter. Friends express and show in action -- and provide the value that you hopefully are also delivering to them. Those friendships are priceless - and few. That's why they are pure gold. Keep well!
